Ive read that matched LEDs are, and are not necessary. Now is this for Vref? or CCS?
I'm just figuring all this stuff out. And also Does it matter if I have more than the required V all my LEDs measure at between 1.895 Vf and 1.915 Vf. So 5 x any of them will be more than 9V for Vref and 3 x any of them will be more than 5.4V for CCS. Or should I just stick'em on the board and not worry?
